RKL:
Just curious why you want to flush and refill now. I just talked to FL and they quoted, 'coolant in 2002 and later motorhomes with CAT engine good for 60 months or 100,000 miles as long as SCA's are checked every 6 months.'
I had the 'itch' to change mine but am reconsidering. Mine has an inline drain petcock and there is a coolant drain, flush and refill procedure in the FL manual that came with the rig.
